    Comments about CARQUEST by Intermotor Knock Sensor:

    Pretty easy install. Not much extra wire on the Subaru which makes disconnect of the plug tricky. The product is excellent and went right on. DO NOT over tighten. It will ruin the part and your day if you snap that bolt.

                    I had the Check Engine light checked. The code meant a bad knock sensor. This part and $75 labor fixed the problem :)

                        Knock sensors are usually located under the intake manifold on the engine block. However with out the presence of your vehicle we cannot provide you with a 100% answer.
